"git svn mkdirs" (which creates empty directories in the current
working copy) can be very slow and is often unnecessary. Provide a
config file option "svn-remote.<name>.automkdirs" that prevents empty
directories from being created automatically. (They are still created
if "git svn mkdirs" is invoked explicitly.)

I hope I have done the attribution correctly. The git-svn.perl file
change is by Junio and the doc and test changes are by me.
Regarding the name of the option: I prefer "automkdirs" to something
like "skipautomkdirs" because the latter is effectively the inverse of
doing something, leading to confusing double-negatives like "if (!
skipautomkdirs)". But I am not adamant about this preference.
For completeness it might be nice to have corresponding command-line
options like --auto-mkdirs and --no-auto-mkdirs, but I doubt that it
is worth the extra effort. If you want to create the directories when
automkdirs==false, you can simply run "git svn mkdirs". It is more
inconvenient if you have automkdirs==true but occasionally want to
skip the creation of the directories, but this seems an uncommon
scenario.
